Abstract: 1380918 Laminated films TOYO BOSEKI KK 29 Dec 1971 [29 Dec 1970 (2)] 60573/71 Headings B5B and B5N [Also in Divisions B2 and B8] A laminate comprises two layers, one of which is made from a biaxially drawn polyamide and the other from a thermoplastic resin which has a melting or softening point at least 50 C. below the melting or softening point of the polyamide. The polyamide contains not less than 70% (mol) of a repeating unit derived from metaxylylene diamine and an α,#-dicarboxylic acid having from 6 to 10 carbon atoms. Up to 30% (mol) of the metaxylylene diamine may be replaced by paraxylylene diamine. The polyamide is obtained by extrusion of a melt, the cooled film being then stretched longitudinally between two rolls and laterally by means of a tenter. The resulting film has specified values of the gas permeability constant, plane orientation index, degree of balance and the breaking and yielding strength and elongations. The second layer, which in Example 7 is polyethylene is extruded on in the form of a melt.

Patent GB-2005761-A (GB)
Title: A door operating appliance
IPC: E05F15/00
Filed: 1978-09-25
Abstract: The reversible electric motor 3 drives the belt 6, pulley 7, shaft 8 and tube 10. The cord 23 wound on the tube 10 has a loop which passes around a pulley above the door and is clamped to the top of, for example, an up and over door. The loop is separated by a slidable plate 24 and as the tube 10 revolves, the guides 25 wind the cord 23 evenly. The tube 10 is hung in a saddle 9 which swings on the rod 12 against spring 18 when the door meets excess load. As the door fully opens or closes, load is partly absorbed by the belt 6 slipping and as the cord 23 tension pulls the saddle 9 forward the belt 6 tightens. The shaft 8 then strikes the lever 26 assembly operating the changeover switch 29. If the saddle further advances, it causes total loss of belt 6 grip. The spring 18 pushes the saddle rearwards, unwinding the core 23 until the ring 31 rubs the friction pad 32, preventing reverse overrun. A lock retains excess cord 23 and operates on cord 23 tension. <IMAGE>
